HHT-WIN vs Xentry vs DAS: which one do I need?

This is a good HHT-WIN review from benzworld.org which tell people what’s the difference of HHT-WIN and Xentry and DAS, which Mercedes vehicle & module HHTWIN supports.

Here you go.

HHT-WIN vs Xentry vs DAS:

Xentry took me to DAS, and DAS switched over (automatically) to good old HHT-WIN, again. Guess my 16-year old SUV’s system is a bit ancient in the scheme of Mercedes-Benz technology.

From what I’ve seen:

All MB from late 80’s to 99 = HHT-WIN

All MB from 2001 to 2009 = DAS

All MB from 2010+ = Xentry

The year 2000 is a weird transition period — some MB made in 1999 but the model year is 2000 will be diagnosed from the 38-pin under the hood and thus use HHT-win. Other MB made in early 2000 and sold as a 2000 model will have the OBD port and the SDS will require the OBD cable to diagnosis….and will use DAS.

And then there are orphan cars, like some SLK models — some 2000-2001 SLK require the 38-pin.

I’ve even seen a 2000 E320 that had both 38-pin and OBD port — I could use either port to conduct a full diagnosis. That was funny.

HHT-WIN supports modules on Mercedes vehicles:

HHT-WIN should be able to read all Modules.

Having said that, for Model Years 1990 – 12/1993, the Roadster Soft Top Module has 30 possible fault codes associated with it.
Whereas for Model Years 1/1994 – 1996, the Roadster Soft Top Module has only 11 possible fault codes associated with it.

IMPORTANT: HHT-WIN is updated to 09.2018 Mercedes software disk. Software released in 2017 and 2018 doesn’t come with HTT-WIN. But now, it comes again!
